Abstract
The utility model discloses a steel concrete combination formula corrugated sheet steel additional strengthening, including the slab that has corrugated groove, at least one steel pipe has been laid in this recess. Pipe gallery structure's the pressure -bearing performance of having add increase that the steel pipe is very big among this steel sheet additional strengthening in main atress structure wave form recess does not still reduce the headroom utilization ratio of structure simultaneously, secondly, prefabricated pin -connected panel is adopted in the invention, convenient and fast, and the project progress is secure, can be applied to under the special working condition such as big buried depth, load are big, large -span, main structure steel thickness can the attenuate under the same operating mode, and reduce cost can bring apparent economic benefits.
Description
Technical field
The utility model discloses a kind of sheet structure, more particularly to a kind of reinforcement of steel-concrete combined type corrugated sheet steel
Structure.
Background technology
Applicant is devoted to always the research and application of steel construction and steel-concrete fabricated structure.That what is applied is many
Patent, it is larger in buried depth, under some working conditions such as load is high, single-span is excessive, common ripple section shape sheet structure originally
It is difficult in adapt to, its structure need to be optimized, strengthens, to meet Practical Project requirement.
It would therefore be highly desirable to solve above-mentioned technical barrier.
Utility model content
Utility model purpose：The purpose of this utility model is to provide one kind and is suitable for that great burying, load is big, large span piping lane
Steel-concrete combined type corrugated sheet steel reinforcement structure.
Technical scheme：The utility model discloses a kind of steel-concrete combined type corrugated sheet steel reinforcement structure, including carrying
The plate of corrugation grooves, is laid with least one steel pipe in the groove.
Wherein, the plate is provided with the closure steel band for blocking groove notch, the closure steel band and corrugation grooves structure
It is located in hollow cavity structure into hollow cavity structure, and steel pipe.
Preferably, the steel pipe is located at the same side of plate.
Preferably, the fill concrete in the steel pipe, or reinforcing bar and fill concrete are set.
Further, the fill concrete in the hollow cavity structure, or reinforcing bar and fill concrete are set.
Furthermore, the plate is flat plate or arc plate.
Preferably, the flexibility of the steel pipe is consistent with the radian of arc plate.
Inventive principle：Invention applies the closed section steel pipe principle higher than the shaped steel torsional property of opening section, pipe
Native common Force principle and concrete filled steel tube principle.The closed section steel pipe original higher than the shaped steel torsional property of opening section
Reason：The shaped steel of closed section in the case of identical cross sectional moment of inertia and section modulus, than the shaped steel of opening section, with bigger
Antitorque, anti-axle pressure, anti-unstability ability.The common Force principle of pipeclay：The corrugated steel of arch, steel pipe and steel-concrete group
Box-like corrugated sheet steel reinforcement structure, can be by native stone around and arcual component cooperative bearing so that apply load in structure
Lotus is converted into interior pressure of the domes along radian direction, similar to stone arch bridge, forms pipeclay and receives stress effect jointly.Steel tube concrete
Native principle：Concrete filled steel tube refers to the fill concrete in steel pipe and the steel pipe and its core concrete that are formed bear jointly
The structural elements of external load effect, it is different by section form, concrete filled steel tube can be divided into, side, concrete-filled rectangular steel tube and many
Side shape concrete filled steel tube etc..Concrete filled steel tube as compression member can give full play to superior compressive property that concrete has and
The superior tensile property that steel have.
Beneficial effect：Compared with prior art, the utility model has advantages below：First, in the steel plate reinforcement structure
The load performance that steel pipe significantly increases Pipe rack is set up in main force structure contoured shaped recess, while also not reducing knot
The headroom utilization rate of structure；Secondly, the present invention adopts precast splice type, convenient and swift, and project progress is secure, can be applicable to bury greatly
Under the conditions of the special operation conditions such as deep, load is big, large span；Under identical operating mode main structure thickness of steel product can with thinning, reduces cost,
Significant economic benefit can be brought.

Specific embodiment
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of steel-concrete combined type corrugated sheet steel reinforcement structure of the present utility model is included with ripple
At least one steel pipe 103 is laid in the plate 101 of groove 102, the groove 102, also many steel can be laid in a groove 102
Pipe 103, and steel pipe 103 is located at the same side of plate 101.
As shown in figure 3, the plate 101 is provided with the closure steel band 104 for blocking the notch of groove 102, the closure steel
Band 104 constitutes hollow cavity structure 105 with corrugation grooves 102, and steel pipe 103 is located in hollow cavity structure 105.
As shown in Fig. 2 in the steel pipe 103 fill concrete, or reinforcing bar and fill concrete are set.
As shown in figure 4, in the hollow cavity structure 105 fill concrete, or reinforcing bar and fill concrete are set.Can
The entire compression ability of plate is enhanced, makes the common plate wall thickness of wall ratio of plate thinning again, so as to further reduce
The cost of material.
The plate 101 of the present invention is flat plate or arc plate.For arc plate when, the flexibility of steel pipe 103 with
The radian of arc plate is consistent.
The steel-concrete combined type corrugated sheet steel reinforcement structure typically can operate with special operation condition Tunnel Engineering, high roadbed
Highway culvert, municipal water supply and sewerage pipeline, Urban Underground pipe gallery, pressure medium conveyance conduit or line layout protection pipeline.
Steel pipe is set up in the pipe gallery in main force structure contoured shaped recess significantly increase holding for Pipe rack
Pressure performance, while also not reducing the headroom utilization rate of structure；Secondly, the present invention adopts precast splice type, convenient and swift, and engineering is entered
Degree is secure, under the conditions of can be applicable to the special operation conditions such as the big, large span of great burying, load；The main structure steel under identical operating mode
Thickness can bring significant economic benefit with thinning, reduces cost.
